With reference to the Radio Frequency Identification (RFID), consider ...
After a high-level security review for the forthcoming Amarnath Yatra, the government has decided to track all pilgrims using Radio Frequency Identification (RFID) tags.
  • Radio Frequency Identification (RFID) is a wireless tracking system that consists of tags and readers.
  • Radio waves are used to communicate information/identity of objects or people to nearby readers – devices that can be hand-held or built into fixed positions like poles or buildings.
  • The tags can carry encrypted information, serial numbers and short descriptions. There are also high-memory tags like the ones designed for use in the aviation industry.
Types of RFID tags
  • Active RFIDs use their own power source, mostly batteries.
  • Passive RFIDs, on the other hand, are activated through the reader using the electromagnetic energy it transmits.
  • Active tags have a longer read range, around 300 ft, compared to passive tags.
Hence both statements are correct.
